Abstract

Asachi Technical University of Iasi. All rights reserved. This study assesses the feasibility of using the filamentous fungus Fusarium solani for the removal of colour, chemical oxygen demand (COD) and total phenols from a pulp mill industry effluent, inoculated in a rotating biological contactor (RBC). The study was done in a RBC of total volume 7.2 L, operated with 40% of useful volume at 37(±2)°C, inflow 3.5 L d-1,ydraulic residence time (HRT) 20 h and rotation speed 2 rpm. A Haldane model was used to determine the kinetic parameters of F. solani with a model effluent. The results show maximum elimination capacities and removal efficiencies for COD and phenols of 2921 mg m-2d-1(84%) and 72 mg m-2d-1(83%), respectively. Colour removal efficiencies of 60% (equivalent to 32 colour units, CU) were also obtained. The kinetic results show COD inhibition at concentrations above 110 mg L-1.
